Two U.S. Postal Service workers were fatally shot at a postal facility in Memphis and a third employee identified as the shooter died from a self-inflicted gunshot, authorities said. It was the third high-profile shooting in or near that west Tennessee city in weeks.

FBI spokeswoman Lisa-Anne Culp said the shooting was carried out by a third postal service worker, who shot him or herself.

No identities or motive were released by Link or Culp at a brief news conference late Tuesday afternoon.

The shooting occurred at a post office facility in the historic Orange Mound neighborhood, southeast of downtown Memphis. The carrier annex is only used by employees.
